When the master sends out the task, it assign a distinct task number ID to the task. When the worker receive the task, it still use the task's assigned ID as task tag to send it to master. Any help is appreciated. July 5 2010

I have used different taskTag to distinguish the tasks, but still does not work. Any help is appreciated. Thanks, Jack July 4 2010 The New Busy is not the too busy.
